The Crypto community unites to help Ukraine. Since Russia invaded the country on February 24, millions of dollars in crypto donations have been pouring into Ukraine from all over the world. 

The drama of Ukrainian society did not go unnoticed. Soon after the Russian troops entered the country, volunteer groups and NGOs opened crypto funds to support Ukrainians with humanitarian help. In just a couple of days, they raised over 5 million dollars in total. 

Ukrainian government started accepting cryptocurrency donations

This small success was quickly followed by Ukrainian officials. On Saturday, February 27, the Ukrainian government used Twitter to ask for cryptocurrency donations to help fight against the Russian military. According to Forbes, it was a matter of just four days before almost $100 mln in crypto were raised.

"We are evacuating people, so we are sending money to buy gas, food, and water for the people who are leaving. We are sending some money to the local military personnel who can buy some supplies locally," said Michael Chobanian, founder of Kuna, a Kyiv-based crypto exchange responsible for setting up the government's digital wallets. 

Initially, the action was focused only on the most popular cryptocurrencies: Bitcoin and Ethereum. Yet over time, the country started to accept a broader range of digital tokens, including Polkadot, Solana, or even Dogecoin. Moreover, the Ukrainian government received a significant number of non-fungible tokens, including some of the most valuable NFTs on the market.

NGOs facilitating crypto donations 

As we mentioned before, the government isn't the only one that collects crypto to help the cause. Numerous Ukrainian and foreign NGOs and private companies started to collect crypto for Ukraine. Aims range from humanitarian help to military funds, depending on the organization's agenda. 

Come Back Alive is one of the most prominent organizations working on the cause. The NGO focuses on supporting the Ukrainian military's response to the Russian invasion. Come Back Alive was previously active on Patreon, from which it was removed due to the platform policy regarding military fundraisers. However, the foundation quickly found its second life thanks to UkraineDAO - a crypto collective raising decentralized aid for numerous Ukrainian organizations. 

"Blockchain allows us to scale our efforts in a way that wasn't possible for us before," said Nadya Tolokonnikova from Ukraine DAO, in an interview with the New York Times. "The old ways of raising money sometimes are really slow and just clumsy."

Military fundraising for many isn't an option, yet importantly, a significant number of such charity collections focus solely on humanitarian help. An example of that is Crypto for Ukraine - an initiative uniting the crypto holders to raise funds for medical assistance, food, hygiene products, and other utilities necessary for survival. Crypto for Ukraine works in direct collaboration with Polish Humanitarian Action. 

Are cryptocurrencies the future of fundraising? 

Without a doubt, cryptocurrency donations are just a small part of financial help sent every day to Ukraine by private donors. Yet, they set a new path for NGOs and charities from all over the world. 

According to Michael Chobanian from Kuna, during this crisis, crypto proved to be more efficient than traditional payment methods. 

"It's tough to [send money] using traditional methods. First of all, it takes a lot of time. Secondly, it's a lot of bureaucracy and so on. Here, we are fast. So we receive money and we spend it almost immediately," he told CoinDesk. 

Cryptocurrency donations - what do you need to know? 

As in the case of any humanitarian crisis, there are individuals that have no compunction about taking advantage of it. Among genuine crypto collections, scams and extortions abound. Therefore, everyone who wants to send crypto must remember about due diligence. You should never trust an anonymous crypto wallet without checking the details. 

Luckily there are crypto projects that can help you on that matter. For example, The Giving Block - a charity curator facilitating fundraising powered by Blockchain technology, which requires a voting process to be featured on the platform

Blockchain for Creators: Secure and Sustainable Infrastructure

Blockchain for Creators: Secure and Sustainable Infrastructure

In today’s digital creative space, where the lines between art and technology are constantly blurring, projects like MARMALADE mark the beginning of a new era - one where creators can protect their work and maintain ownership through blockchain technology.

For Nextrope, being part of MARMALADE goes far beyond implementing features like screenshot blocking or digital watermarking. It’s about building trust infrastructure - systems that empower creators to thrive in the digital world safely and sustainably.

A new kind of blockchain challenge

Cultural and educational projects come with a completely different set of challenges than typical DeFi systems. Here, the focus isn’t on returns or complex smart contracts - it’s on people: artists, illustrators, educators.

That’s why our biggest task was to design secure yet intuitive infrastructure - lightweight, energy-efficient, and accessible for non-technical users exploring Web3 for the first time.

“Our mission wasn’t to build another financial protocol. It was to create a layer of trust for digital creators.”
— Nextrope Team

Security that stays invisible

The best security is the kind you don’t notice.
Within MARMALADE, we focused on making creators' protection seamless:

  • Screenshot blocking safeguards artworks viewed in browsers.
  • Dynamic watermarking helps identify unauthorized copies.
  • Blockchain registry ensures every proof of ownership remains transparent and immutable

“Creators shouldn’t have to think about encryption or private keys - our job is to make security invisible.”

Sustainability by design

MARMALADE also answers a bigger question - how to innovate responsibly.
Nextrope’s infrastructure relies on low-emission blockchain networks and modular architecture that can easily be adapted for other creative or cultural initiatives.

This means the technology built here can support not only artists but also institutions, universities, and educators seeking to integrate blockchain in meaningful ways.

Beyond technology

For Nextrope, MARMALADE is more than a project — it’s proof that blockchain can empower culture and creators, not just finance. By building tools for digital artists, we’re helping them protect their creativity and discover how technology can amplify human expression.

Plasma blockchain. Architecture, Key Features & Why It Matters

Plasma blockchain. Architecture, Key Features & Why It Matters

What is Plasma?

Plasma is a Layer-1 blockchain built specifically for stablecoin infrastructure combining Bitcoin-level security with EVM compatibility and ultra-low fees for stablecoin transfers.

Why Plasma Blockchain Was Created?

Existing blockchains (Ethereum, L2s, etc.) weren’t originally designed around stablecoin payments at scale. As stablecoins grow, issues like congestion, gas cost, latency, and interoperability become constraints. Plasma addresses these by being purpose-built for stablecoin transfers, offering features not found elsewhere.

  • Zero-fee transfers (especially for USDT)
  • Custom gas tokens (separate from XPL, to reduce friction)
  • Trust-minimized Bitcoin bridge (to allow BTC collateral use)
  • Full EVM compatibility smart contracts can work with minimal modifications

Plasma’s Architecture & Core Mechanisms

EVM Compatibility + Smart Contracts

Developers familiar with Ethereum tooling (Solidity, Hardhat, etc.) can deploy contracts on Plasma with limited changes making it easy to port existing dApps or DeFi, similar to other EVM-compatible infrastructures discussed in the article „The Ultimate Web3 Backend Guide: Supercharge dApps with APIs".

Gas Model & Token Mechanism

Instead of forcing users always to hold XPL for gas, Plasma supports custom gas tokens. For stablecoin-native flows (e.g. USDT transfers), there is often zero fee usage, lowering UX friction.

Bitcoin Bridge & Collateral

Plasma supports a Bitcoin bridge that lets BTC become collateral inside smart contracts (like pBTC). This bridges the security of Bitcoin with DeFi use cases within Plasma.
This makes Plasma a “Bitcoin-secured blockchain for stablecoins".

Security & Finality

Plasma emphasizes finality and security, tuned to payment workloads. Its consensus and architecture aim for strong protection against reorgs and double spends while maintaining high throughput.
The network launched mainnet beta holding over $2B in stablecoin liquidity shortly after opening.

Plasma Blockchain vs Alternatives: What Makes It Stand Out?

FeaturePlasma (XPL)Other L1 / L2
Stablecoin native designusually second-class
Zero fees for stablecoin transfersrare, or subsidized
BTC bridge (collateral)only some chains
EVM compatibilityyes in many, but with trade-offs
High liquidity early✅ (>$2B TVL)many chains struggle to bootstrap

These distinctions make Plasma especially compelling for institutions, stablecoin issuers, and DeFi innovators looking for scalable, low-cost, secure payments infrastructure.

Use Cases: What You Can Build with Plasma Blockchain

  • Stablecoin native vaults / money markets
  • Payment rails & cross-border settlement
  • Treasury and cash management flows
  • Bridged BTC-backed stablecoin services
  • DeFi primitives (DEX, staking, yield aggregation) optimized for stablecoins

If you’re building any product reliant on stablecoin transfers or needing strong collateral backing from BTC, Plasma offers a compelling infrastructure foundation.

Get Started with Plasma Blockchain: Key Steps & Considerations

  1. Smart contract migration: assess if existing contracts can port with minimal changes.
  2. Gas token planning: decide whether to use USDT, separate gas tokens, or hybrid models.
  3. Security & audit: focus on bridge logic, reentrancy, oracle risks.
  4. Liquidity onboarding & market making: bootstrap stablecoin liquidity, incentives.
  5. Regulation & compliance: stablecoin issuance may attract legal scrutiny.
  6. Deploy MVP & scale: iterate fast, measure gas, slippage, UX, security.
